The Partita in D minor for solo violin (BWV 1004) by Johann Sebastian Bach was written between 1717 and 1720. It is a part of his compositional cycle called Sonatas and Partitas for Solo Violin.
Professor Helga Thoene suggests that this partita, and especially its last movement, was a tombeau written in memory of Bach's first wife, Maria Barbara Bach (who died in 1720), though this theory is controversial.
